Sno Pro gets all the same lightweight parts as the Mnt Cat. Only difference is the Mnt Cat has a different shock package (same length), led headlight and a goggle bag. Also the Sno Pro you can get a 2.6" or 3" in the 153" length but both get 3" in the 162".
Snow show in Denver this weekend would be a great spot to get more info directly from Arctic Cat. Front Range Powersports out of Ft. Collins is great and will be at the show as well.

There is a lot of different info out there, I thought that tank was specific to the MC, but I have also read all Non-ES SO and MC received it.
This was directly from arcticinsider:
It’s been three straight years of serious improvement on the M Series machines, with 2018 getting perhaps the biggest upgrades that result in a 10-15-lb. weight reduction depending upon model.
The improvements:
* Body panels are 3-in. narrower (and 1-lb. lighter) which lets you carve deeper in the snow without levering off the panels;
* Lightweight aluminum drive shaft (3-lb. weight savings);
* Hollow driven shaft (2.25 lbs. lighter);
* 5-lb. lighter gas tank (on Sno Pro/Mountain Cat non-electric start models);
* And a lightweight brake assembly that drops 1.3 lbs.
Plus all 2018 M sleds get the upgrades that came on the 2017 Mountain Cat (and which shed about 6 lbs.). These changes are referred as the Ascender Platform:
* A driveshaft that’s 1-in. lower and 0.75 in. rearward, which results in a flatter track-to-snow angle for improved floatability, quicker climbing on top of the snow while accelerating and improved handling. It makes possible the 3-in. lug track and 8-tooth drive sprockets;
* Revised running boards are 1-in. narrower for improved side-hill performance
* Revised bellypan shape allows the rider’s feet to move 2 in. further forward
* Thinner gauge aluminum on the rear tunnel, plus strategic cut-outs on the front tunnel section
Last year the Mountain Cat was the lightest M Series model, and now it sheds another 16 lbs. for 2018!
